Sanitary pH Sensors & ORP Sensors for Tri Clover Installations Requiring Chemical Clean-In-Place (CIP) Sterilization

Unique solutions for process measurement problems. Features & options itemized below:

• Best reference service lifetime in process industry through proprietary, novel, non-porous, cross-linked, conductive polymer technology; Available in double junction (standard) or triple junction (optional “TJ”) configurations

• Rugged industrial grade sensors can operate in a temperature range from -35 to 150 degrees Celsius at pressures up to 200 psig

• Base models for general purpose, high temperature resistant, ultra-high temperature resistant, slurry & viscous material resistant, acid/fluoride & HF resistant, pulp & paper resistant, aggressive dissolved gas & volatilve organic solvent resistant, Oxidation Reduction Potential (ORP) and saturated sodium (brine) resistant

• Selected optional features include Ammonia gas resistant (“A”), Chlorine gas resistant (“C”), Wide Range -0.5 to +14.5 pH Media Resistant (“V”), Organic Media Resistant (“L”), Solvent Resistant (“TS”), 3-Wire TC (“M”), ACCU-TEMP Fast TC (“X”), Add Protective Tines 4 ea (“GR”), Add Protective Tines 2 ea (“GRO”), Shielded Preamp Cable (“BL”)

• Available with integral TC (Pt100/Pt1000 Standard), Solution Ground Liquid Earth (316SS or Platinum), Dual pH/ORP All-In-One Configuration and Conventional or Differential Analog preamplifier to allow for interfacing with most any existing OEM transmitter

• End of cable terminations include tinned leads, BNC connector for pH sensors and ORP sensors without integral preamplifier. Quick disconnect snap connector options are available for pH sensors and ORP sensors with integral preamplifiers.

• Convenient Quick-Disconnect Tri-Clover fittings allows easy calibration and cleaning in any process

• 316SS Sanitary Sensor Fitting available in 1.5", 2.0" or 2.5" Tri-Clover sizes (other larger sizes available upon request)

• Alternate fittings can be welded upon request such as 1.25" MNPT threaded nipple for high-pressure inline screw-in installations

• Double sealing O-rings ensure watertight seal Viton®-75 is standard with CV75, Simriz® 485 and Kalrez® 4079 Optional

• Back of sensor sealed with watertight cable gland to ensure watertight operation from washdowns, moisture and outside installations

• Each standard sensor selection and/or special sensor design are based upon customer application information

• pH sensors & ORP sensors are manufactured with rugged RADEL® (Poly-Phenyl-Sulfone, PPSU), KETASPIRE® (Poly-Ether-Ether-Ketone, PEEK) or RYTON® (Poly-Phenylene-Sulfone, PPS) for sensor body housing material of construction

• Solid state reference highly resistant to dehydration. Thick wall glass is nearly impervious to cracking even under pressure.

• Rugged parabolic thick-wall, low-profile, break-resistant pH glass is now standard for all X3XX series pH sensors.

• Extreme Dehydration Resistant Option can be invoked with Alpha Prefix “E” on supported sensor models to allow for intermittent wet and dry operation as well as to support periods of exposure to prolonged dryness in the field or shelf

Replacement pH & ORP Sensors For Transmitters that support and/or require Integrated Preamplifiers

The instruments listed below require and/or support integral preamplifiers. Sensors to mate with these OEM pH & ORP transmitters are supplied with the appropriate integrated temperature compensation element, solution ground & OEM compatible high-impedance CMOS operational amplifier (a.k.a. preamplifier) as may be required to ensure full compatibility and optimal performance. Some manufacturers and analyzer models can support both sensors with or without preamplifiers on the same instrument. A sensor hook-up schematics for interfacing to the given OEM pH/ORP transmitter is supplied with each sensor, and some of the most common wiring schematic are posted on our website (please inquire for any not listed).

Replacement pH & ORP Sensors For Transmitters DO NOT SUPPORT Integrated Preamplifiers

The instruments listed below do no support preamplifiers. Sensors to mate with these OEM pH & ORP transmitters are supplied with the appropriate internal temperature compensation and/or solution ground signals to ensure compatibility. A sensor hook-up schematics for interfacing to the given OEM pH/ORP transmitter is supplied with each sensor, and the some of the most common wiring schematic are posted on our website (please inquire for any not listed). If longer cable runs may be required for your planned installation, it is recommended to select a transmitter that supports preamplifiers (see list to the left).
